dear george the cpu is very fortunate and more I use ice water temperatures about 2 degrees . in this benchmark the load on the CPU is minimal then 5.3 are possible , of course on a benchmark where the load on the CPU is increased , such as Texture integration , I can not go beyond 5GHz . moderators said the benchmark is valid then live peaceful and remember that if you can not do you not said that can not nobody do it . ps . my uncore 1,60v does not need to be stable at 5GHz , but it only takes 1,38v so kindly if you do not know that there cpu like mine , avoid calling me a cheater because I'm no cheater is you who are ignorant
